Abstract
The paper presents a mathematical model which describes the operating modes of rotary positive displacement pumps and motors. The model is worked out by considering the commutative processes taking place in the chambers formed by the moving and the stationary parts of the machine, which in particular can be pistons and barrels. The obtained analytic dependency enables the assessment of the performance parameters variability during steady-state operating mode of the hydraulic unit.
